- Be it known that I, JAMEs'A. KEYEs, a citizen of the United States,and a resident of New York city, in the county and State of New York,have invented certain new and useful Im rovements in Packing-Machines, lie followin is a specification, taken in connection with theaccompanying .drawings, which form a part of the same. This inventionrelates to packing machines, and relates especially to machines in whicharticles, such as Wra ped packages, are supplied along 'a chute in t epath of a transferrmg-plunger which operates to succes sively transferrows-of these articles to a carrier. This carrier in the embodiment ofthe invention illustrated is actuated when acomplete layer of articlesis supplied to it to insert this layer into a box or receptaclesupported in suitable guides ad'acent the car- I rier, the box being fedforwar intermittently by suitable mechanism.

In-the accompanying drawings, in which the same reference-numeral refersto'similar parts in the several'figures, Fi view of an embodiment of t's invention.

Figsfi,7, and 8 are details.- Fig. 9 is a longitudinal sectional view showingthe box-feeding mechanism.

Fig. 10 is a transverse sectional view of'the" same. Fllgllisadetail.

In-the lustrated embodimentof this invention wrapped articles 318 areindicated as being fed along thechute 325, and these arti- 'cles mayissue from a suitable wrapping-mao e trans-. I ferrmg-plunger 219ismounted-ad'acent this chine in which they-are formed. J

- chute to transfer articles to the a jacent table 225. "(IndicatedinFig. 5.) This pluner 1s supported-upon the-rods 220, mountedin the lugs221, and is connected by the short link 218 with the plunger-arm 217,which is shown as pivoted about thepin 238. f The plun er-crank 215v isloosely mounted uponthe p unger-shaft 205 and is connected by the hnk216 with the plunger-arm mentioned, so

that upon th'e rotation of this crank the plungel is reciprocatedthrough this' conneeting mechanism. A' suitable trigger222'ismountt edinthe path of the articles, this trigger being indicated as secured tothe trigger-shaft 223, which is mounted-in suitable bearings in re 1 isa side.

clutch 207 which is indicated in Fig. 6 as pivoted about the pin 208 inthe lug 206, securedto the shaft. This clutch 207 is spring- 209 in thesleeve 210 of the plunger-crank, so that when this clutch 207- is in theengaged position indicated the plunger-crank 1s rotated by the shaft205, and the plun er is thereupon reciprocated. The elevate portion 211of the clutch-slide 213 is formed of such height that when the parts arein the position indicated in Fig: 1 the tail of the pawl or dog 207 isengaged by this part of the slide 213, and the pawl is thereupon raisedout of engagement with its cooperating notch and the As soon, owever, asthe trigger is en aged by the leading article in the c slide 13 ismoved, so that the-lower depressed eration with the pawl, which isthereupon a lowed to engage-the notch 209, the parts assuming theposition indicated Flg. ,6 and cated.

The receiving-table 225 is mounted on the rigid frame of the machine,comprising the numbers 320, 321, and 322, and is formed with suitablegrooves which su the reciprocating inserting-carrier. e'cated as havinits bottom formed of a series of' lates274, tting within the s1ides',of-th'e tab e, and thus accurately guided carrier is preferably giventhe inclosed form indicover 273 272 to form an inte 31 structure. Therods 3.23 may be secure to the carrier andpass serving tosupport thecarrier when in its ad- Vance position. Any desired means inlay be usedfor operating this carrier, the links pressed, so that it tends toengage the notch.

pllunger crank remains stationary.

ute the c utchcarrier 1s mdi-z through suitable bearings 319, these rods270 being indicated as pivotedlto the lugs 271 on the carrier-back 272andbeing connected This slide is mounted on .and drive-shaft 20 1carries the spring-pressed portion 212 of this slide is moved into coothe transferring-plunger 219 being reciprocated in Fi 2, the bottomplates 274 and the eing rigidly secured to the back at their other endsto the arms 269 on the rock shaft 268, which is mounted in the brackets275. The arm 267 on this rock shaft is connected by the link 266 withthe crank 265 on the cam-shaft 257. The gear 256, which is secured tocam-shaft 257, meshes with the driving-pinion 255, which is looselymounted on the drive-shaft 201 and operatively connected therewith atthe proper intervals by a suitable pawl mechanism.

The latch-bar 242, which is mounted in the path of the leading row ofarticles in the carrier, is preferably formed with the notches 243,(indicated in Fig. 3 so as to accommodate the folds of the wriippers onthese articles. This latch is mounted on the latch-bar 240, secured tothe latch-rod 241 and normally held inward in o erative osition by thespring 314. This atch -rod whose outer end is mounted in a suitablebearin in the member 2440f the frame, carries the atch-finger 245. Theouter end of this finger engages the pivoted detent 246, wihch is shownin Fig. 8 as engaged by the spring 249 and pivoted about the in 248.

'T e pawl mechanism used to connect the driving-pinion 255 with thedrivin -shaft 201 comprises the spring-pressed paw 250, pivoted in thelug 251 on the drive-shaft and adapted to engage the notch 254 in thesleeve 253 of the pinion. As long, however, as the latch-finger engagesthe detent and holds it in the position indicated in full lines in Fig.

-8, the pawl 250 is held out of, en a ement with the cooperating notch254 an t e pinion is disengaged from the drive-shaft, theinserting-carrier being thus maintained in inoperative position. When afulllayer of articles has, however, been transferred to the carrier, theleading row of these articles engages the latch-bar 242 and through theconnecting mechanism described lifts the latchfinger 245 away from thetail of the detent, the parts thereupon assuming the dotted positionsindicated in Fig. 8 and the nose of the pawl 250 being spring-pressedinto engagement with the notch 254. The carrier is thereuponreciprocated and inserts the full layer of articles into the box,thelatch and clutch mechanism being held in o erative position during thisinterval by any esired means. As indicated, the link 270 is shown asformed with its outside face substantially flush with the back of thecarrier, and the latch-bar 242 is adapted to ride upon the outside faceof this link, and thus maintain the latch in proper position until thecarrier once more resumes its receiving position. (Indicated in Figs. 2and 3.) Then the latch-bar is pressed forward by its sprin and thelatch-finger 245 rides down the-inc ined portion 247 of the detent, andthe parts of the pawl mechanism once more resume the position indicatedin full lines in Fig. 8.

A suitable stop is preferably provided to remove the articles from thecarrier on its rearward movement, so as to leave these articles inposition in the box. A series of stopfingers 264 may be employed forthis purpose and may be mounted upon the arms 263, operating in theslots 315 and secured to the shaft 261, mounted in suitable bearings inthe lugs 262. The arm 260, which is also secured to the shaft 261, isprovided at its outer end with the roller 259, which engages the stopcam258 on the cam-shaft 257. By this means the sto -fingers 264 arewithdrawn below the level 0 the table 225, when the inserting-carriermoves forward into thebox; but as soon as its rearward movementcommences the stop-fingers rise through the slotted bottom of thecarrier in front of the articles therein and discharge these articlesfrom the carrier, leaving them in proper position in the box. A suitablestop may also 'be employed between the chute 325 and the table 225 tokeep the articles transferred into the carrier in roper alinement. Thissto may take the orm indicated in Figs. 5 an 7, the stop 235 beingindicated as formed with suitable rods 233 at its lower end, which aremounted in guides in the brackets 234. The link 232 connects this stopwith the rock-lever 231, pivoted about the pin 237 and engaged by thespring 236 indicated. The free end of this rock-lever cooperates withthe cam 230, formed on the sleeve .210 of the plunger-crank 215 on shaft205, so that when the transferring-plunger 21,9 begins to move forwardthe stop 235 is momentarily withdrawn by the cam below the surface ofthe table. Thereafter the spring 236 raises the stop behind the articlesinto engagement with the under surface of the plunger and as the plungermoves backward the sto moves upward into the notch 358 and ho ds thearticles in position in the carrier, thus engaging them before thearticles are released by the plunger.

The box-guide 296 is rigidly secured to the frame and serves to keep theboxes 324 in proper position as they are fed downward into cooperationwith the inserting-carrier. Suitable feeding means which may take theform of the feed-chains 287 are mounted adjacent the box-guide and serveto control the feed of the boxes in the machine. As seen in Figs. 9, 10,and 11, each feed-chain 287 is mounted upon the sprockets 289, securedto the shafts 285, the lower shaft being connected by the bevel-gears284 283 with the transverse feed-shaft 282, so that the feed-chains areoperated in unison. A series of springpressed lugs 288 are secured tothe chains, these lugs, as indicated in Fig. 11, being pivoted about thepins 327 and being provided with a suitable spiral spring 330, the endof each lug operating in a suitable slot 328 in the pivot link 329 ofthe chain. These lugs are spaced apart on each chain at distancescorresponding with and equal to a multiple of ITO sides of the boxes.

tances being different from the height of a box and preferably beingless than the height of a box by asufficient amount to compensate forthe thickness of the adjacent As is seen in Fig. 1, the

feed-shaft 282 is opgrated by a suitable sprocket-chain 280,

W ch passes through the aperture 317 and is driven by the sprocket 279on the stop-shaft 278. This shaft is intermittently rotated by a Genevastop-motion, the roll on the lug 276 upon the camshaft engaging theradial slots in the starwheel 277 on the st p-shaft, so that every timethat the insert g-carrier operates the boxes are fed downward a distancecorr'e-' s ondin to the thickness of a layer of arties. T e ivote'ddischarger 295, which receives the led boxes, is mounted upon the shaft293, running in the bearing-lugs 294 and v which is operated by the arm292, secured 290 on the stop-shaft by the link 291.

thereto an connected with a suitable crank This discharger is arranged.to receive the filled boxes when they are released by the feed-lugs andto swing them out of the boxuide, as is indicated in Fig. 9, so thateach led box is turned upward with its open side' uppermost and is laidon the conveyer 308, resting on'the sprocket-chains 302 and 303,- whichcarry it away. As is seen in. Fig. 2, the'chains 302 and 303 pass overthe s rockets 305 on the shaft 306, supported by t ebrackets 307, andover the idle sprocket 304 and the drivings rocket 301, secured to thesleeve 300 on the s aft 357. This sleeye is connected with the srocket-wheel 299, engaged by the sprocketc ain 298, which also engagesthe sprocket 2971on the drive-shaft 201. (See Figs. 1 and 3.) After eachlayer of articles hasbeen inserted into the box-the box-feed operates tofeed the boxes downward a distance conesponding to the layer of articlesinserted, the

boxes being normally supported, as indicated in Fig. 2, by thespring-pressed lugs 288, which snap outward mto supporting osition atright an les to the chain. (See igs. 10 and 11.) These lugs are adapted,however, to be swung backward into ino erative osition bv engagementwith the sidies of the ox, as is s own; in Fig. 10. When, however, the

, filled box is swung outward in the direction indicated in Fig. 9,these lugs as soon as the I filled, box moves out of engagement withthem snap outward int'o supportingposition. The lugs thus engage theempty box,'-which descends upon them and which is fed downhold thearticles in position in the box, the

ward at unlform intervals until it is filled and remoyed from the guideby the discharger.

series of retainers may be employed to retainer-arms 313 being shown inFig. 5 as securedtothe shaft 316,mo unted in suitable bearing'si The arm310 on this shaft engages the retainer-cam 309 on the feed-shaft 282,and this cam allows the retainers to be thrown forward at the time thatthe discharger removes the box from the guide by the spring 312, whichengages the arm 311 on the retainer-shaft. The articles are thus held inproper position in the box at this time, and the retainers also serve tokee the articles in alinement as the partiallyed box is fed down pastthem.

It is of course understood by those familiar with this art that manymodifications may be made in the form, proportion, and number of partsof this machine. Furthermore, parts of the same may be omitted and partsmay be employed in connection with other devices without de arting fromthe spirit of this invention or l bsing the advantages of the same.
